What do a vacuum cleaner, a Hussarya and train travel have in common?

Vehicle aerodynamics is a research field with extremely dynamic advancements - both in the racing and road vehicle categories. It is related not only to vehicle performance, but also to issues of safety, comfort, and driving economy. A tool that, in the last decade, has become complementary to classical research methods, such as tunnel testing, is computational fluid mechanics (CFD). During the seminar, a wide range of possibilities for using CFD tools will be presented.  It will explore methods for testing active aerodynamics components, present study work on the concept of novel downforce generating systems, and end with the results of a study of the flow around a MotoStudent class motorcycle and the effect of crosswinds on a moving passenger train.
